How Does Tpws Work?

I know how other safety systems work, but I don't know how TPWS works

Effectively, it puts the emergency brakes on if you pass a red signal, or if you approach a red signal or buffer stop too quickly. The driver does not need to acknowledge anything in normal service.

 

Thank you! Now I can use TPWS properly (even if I didn't use it)

 

What a smart noob you are!
